The ECU of a STEYR MOTORS marine engine can be verified for proper functioning using the Electronic Management System (EMS). The EMS performs self-diagnostics to protect the engine from damage and stores diagnostic data. To check if the ECU is functioning properly, follow these steps:

1. Check for Error Codes: The EMS system records diagnostic and abuse data. Connect a diagnostic tool to retrieve any stored error codes.
2. Monitor Engine Performance: Ensure engine functions, such as fuel injection and power output, operate correctly.
3. Inspect for Warning Signs: Reduced engine power or warning indicators may suggest an ECU issue.
4. Consult a STEYR Marine Dealer: If issues persist, seek professional diagnostics and repair.

Proper diagnosis requires following STEYR’s service guidelines.

Page 28: B Specifications
SERVICE MANUAL MARINE ENGINES GENERAL Specifications Fuel Requirements The STEYR Marine Engines are designed for maximum fuel economy. To maintain optimum performance use diesel fuel according to CEC RF-03-A-84 or equivalent to meet this specification. When temperatures are below -7° C (20° F), use diesel fuels with additives for low temperature operation. How to Select Fuel Oil Fuel quality is an important factor in obtaining satisfactory engine performance, long engine life, and acceptable exhaust emission levels.
Page 29: B 2 Motor Oil
SERVICE MANUAL MARINE ENGINES GENERAL B 2 Motor oil To obtain the best engine performance and engine life, only motor oils of know manufacturers are to be used, with ACEA, API service code and specified SAE viscosity.
